IMPROVEMENT IN AUTOMATIC BOILER-FEBDERS.

AThe Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that we, J CHN R. WIDGEON andFRED. E. FREY, of Bucyrus, Crawford county, Ohio, have invented a newand improved Construction of Automatic Boiler-Feeders; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof', which will enable others skilled -in the art to make and usethe same, reference `being had to the accompanying drawings, formingpart of this specification.

Figure 1 represents a vertical section of this invention, taken in theplane indicated by the linexs'c, iig. 2.

Figure 2 is a plane or top view of the same.

Figurel 3 is a front elevation of the driving-gear detached.

Figure 4 is a face view of the seat detached.

.Figure 5 is an inside elevation of the revolving chamber. 'y

Figure 6 is a perspective View of the insidel and partially of theoutside of a case which encloses the automatic boiler-feeder, indicatedby figs. 1, 2, 3, 4,

` and 5, and which is described in Letters Patent issued to said JOHN R.WrnGEoN and FRED. E. FREY, March 13, A. D. 1866, and the specificationsthereto attached.

Figlue 7 is a small steam-pipe, p', leading from pipe h, tig. l, intothe interior of the casing Q, iig. 6.

This present improvement vconsists in the construction of boer-ieedersof that class in which a revolving chamber is used steam-tight.

A represents a chamber, made of metal or any other suitable material,and provided with a `solid bottom, a, and top b, and also with a toothedrim, c. This chamber revolves ou a centre-pin, d', and its bottom, a,works steam-tight against the seat B, which is composed ot' a thicklatplate, perforated with four holes, l e fg, as seen in fig. 4. Theopening,'e, communicates, through the pipe h, with the steam-space, andthe opening, g, through a pipe, t, with the water-space of asteam-boiler. From the hole (Z leads a pipe, j, to the open atmosphere,and another pipe, k, leading from the hole f to the water-tank, servesto introduce the required supply of water into the chamber A. Saidchamber is provided with the ports im, one diametrically opposite theother, and as said chamber revolves, these parts alternately coincidewith the holes d and j, and then with the holes c and g and the seat.

The revolving motion of the chamber A is produced by a cog-Wheel whichgears in the toothed m'm c of said chamber. Said cog-wheel is mounted ona shaft, o, which has its bearing in a standard, p, rising from theplate which forms the seat B. When the ports l m are opposite the holese g, the upper part of the chamber tills with steam, and a portion ofthe .water in the chamber runs down in the boiler, and this operationcontinues until the water in the boiler rises To keep the bottom, a,ofthe revolving chamber A close and steam-tight against the seat B, andprevent' the weight of steam from pressing said bottom of the chamberfrom said seat, and thus permitting the escape of steam, we haveprovided the case Q, which sets over said revolving chamber A, and isscrewed fast to the seat B by screw-bolts q q q q, tre-pin al to passthrough a packing-box at the outer end of said case Q. p is a smallsteam-pipe leading from pipel h into the interior of case Q, whereby tointroduce steam into said case, which, by its pressure against the topof the revolving chamber A, counter acts the pressure of the steam atthe bottom of said revolving chamber; and whilst the steam introduced bythe pipe It through the opening c, has a great tendency to part thebottom of said revolving chamber A from close contact with said seat B,and permit the escape of steam between the two faces aforesaid, our

device of the case Q, and filling the. same with steam by means of thepipe jp', has an equal tendency to keep said two faces together, andprevent the escape of steam.

O' is a cock by which steam, and Water of condensed steam, may be drawnout of said case when desired.

fr is a set-screw by which the pressure of the bottom of said revolvingchamber A against said seat B may be slackened should there be too heavya pressure.

S is a spiral spring coiled around the centre-pin d, and pressed betweenthe top of said revolving chamber A and the intelior end of said case Q,serving tov keep the bottom of said revolving chamber against said seatwhen no steam is in said case 5 otherwise said two faces might part andpermit the steam from pipe p', on its introduction into said case Q, topress against the bottom as Well as the top of said revolving chamber A,and prevent its operation.

What we claim as our invention, and desire to secure by Letters Patent,isv

The combination of the case A, having ports Z m, and with the seat Bprovided with holes d c f y, substantially as herein described.
